Notes on Behaviors

Types And Species

Attack Type means that a monster will attack a monster of the same type (for example, a Blue Tridude and a Red Tridude are of the same Monster Type) and Attack Species means that a monster will attack another monster of it's same species (for example, a Green Tridude and another Green Tridude are the same species)

Unusual Monsters

Monsters of the type "Unusual" that have an AI Type which does not include the "Attack Type" behavior may still attack other "Unusual" type monsters. This is an exception to the "Attack Type" behavior, since the "Unusual" Monster Type is a catchall category for monsters without a specific type, and not intended to be an actual category of monsters.

Behavior vs Abilities

Behaviors associated with an AI Type only affect what a monster of that AI Type will do when controlled by the Game AI. Not having a behavior does not mean the monster is incapable of performing that action when possessed, polymorphed, or otherwise directly controlled by the player.

Mechanical Mice

Mice have a unique pattern: They try to follow a wall, keeping it on their right. For this purpose, any sort of obstacle counts as a "wall" -- liquid tiles, boulders, even monsters or the avatar. If no "wall" is to their right, they will check for a wall behind and to their right (that is, they are turning a corner). Otherwise, they will keep going straight until they find a wall, then follow it to the left. If they cannot do any of the above, they are considered "cornered", and will revert to a normal AI long enough to get them out of the corner. This last is the only case in which they can attack, assuming they've been angered. This fixed pattern means that a pet mouse cannot obey commands (notably "Stay"), though they might be able to attack something if they happen to get cornered by it. A possessed mouse, or polymorphed avatar, can still move normally at the player's direction.
